U.S. Justice Department lawyers will ask a federal appeals court in Washington to block a lawsuit from Democratic U.S. senators and House members that contends President Donald Trump is violating the U.S. Constitution’s prohibition against presidents receiving gifts or payments from foreign states.

Justice Department lawyers have lost earlier bids to shut down the lawsuit, filed in U.S. District Court for the District of Columbia by named plaintiff U.S. Sen. Richard Blumenthal, D-Connecticut, who was joined by more than 200 other senators and members of the House. Government lawyers said Monday they intend to ask the U.S. Court of Appeals for the D.C. Circuit to issue an order pausing the case, or an order directing the trial judge to dismiss the complaint.
